IMPROVEMENT IN COP-WINDERS.

Specification forming part of Letters Patent No. l 79.488, dated July 4,1876; application led April 10, 1876.

To all whom 'it lmay concern:

Be it known that I, WILLIAM REID, of Glasgow, in the county of Lanark,Great Britain, have invented an Improvement in the `Wind ing of HollowCops of Thread for use in shuttles of sewingmachines5A and the followingis hereby declared to be a full, clear, and exact description of thesame. This invention consists, generally, of a new or improved means ofwinding the under threads for sewing-machines into the form ot hollowcops for use within the shuttles, so that they uncoil or unwind from theinside; and under these improvements far more thread can be put into theshuttle than hitherto, and the stoppages and breakages are greatlyreduced thereby; and I do hereby declare that the following is a fulland correct description thereof, which will enable others skilled in theart to make and use the same.

Figures 1 and 2 on the accompanying drawings are afront elevation and aplan ot' a simple single spindle-winding machine, and Fig. 3 is a sideview of the cop-winding spindle detached, all for winding the improvedhollow cops of thread (one at a time) for use in the shuttles ofsewing-machines, and for being unwound from the inside, as shown in sideelevation detached in Fig. 4 5 and all constructed in accordance with,and illustrative of, one mode and means of carrying my said inventioninto effect or practice.

Referring to these, Figs. 1, 2, and 3, the machine consists of theactual winding-spindle l, (shown in Fig. 3,) slightly tapered toward thepoint at the part l',on which the cop of thread a, Fig. 4, is wound.This spindle 1 may either be formed in one with or be secured to thelarge central part 1" with the head or collar 1"', by which it isshifted longitudinally within its hollow drawing-spindle 2, which, forthat purpose, is connected to the body part l" of the spindle 1 by a pinand slot, 2', and mounted to revolve freely in the two journal-bearings3 ot' the headstock 3', formed or secured on the upper part ofthe frame4, carrying the whole, and which may be secured, by screws at 4', to asewing-machine table or other table or frame at a proper height for theattendant to attach the thread and remove the cops ct as they areuished. The spindle 2 is driven by a cord, 5, passing from adriving-pulley on the actuating-shaftoi the sewin g-machine, or othersuitable motive-shaft, round 'the fast or the loose pulley 2" 2"'mounted on its one end, so as, by its slot-and-pin connection beforementioned, to actuate the spindle in the direction indicated by thearrows in these figures. The

spindle 2, by a screw, 6, fast on its one end and working into ascrew-wheel, 6', also actuates the vertical spindle 7 carried in thebearings 7' 7" of the frame 3' and 4, and which, by a heart-cam, 8,keyed on its lower end, actuates the slide 8' working in guides in thelower side of the bearing-bracket 7", and a connecting-rod, 8", throughthe anti-friction pulley 8"' attached to the said slide 7', in onedirection, against the power of the spring 8"", which actuates them inthe other direction, the one end of the spring being attached to the rod8"' and the other end to a hook on the end ofthe stationary frame 4, andthe free end ot' the connecting-rod S" is connected by a pin andsegmental slot to the pendent arm of the bellcrank 9, fulcrumed on astud, 4", projecting from the front of the frame 4, in a transverseplane with the center ot' the tapered part of the spindle l, where thecop a is wound, and the `arm of this crank has the laying-on finger oreye 9" attached to it, through which the thread is fed from the reel orhank, or from large bobbins or pirns, through tension-regulatingspring-disks 9"', or other equivalent, (seen only in Fig. 2,) on its wayto the eye 9" and winding-spindle 1', which lays on the thread regularlyfrom end to end of the tapered part 1' of the spindle 1 1' as theheartmotion 8 actuates it. The conical point ot' the spindle l' works ina small recess in the stead ying collar or bush 10 carried in thestandard l0' projecting up from the frame 4, so as to steady it andbuild the cop et with a fiat end, the other end ot' the cop a being alsobuilt fiat close up to the collar 1l on the extreme end of the spindle2, which has mounted on it, behind the collar, two tension-disks, 12,with a pressing spiral spring at the back as a griper for the end of thethread, which, after being inserted through the eye 9", is fixed andheld between the disks 12, and the cord 5, being shifted onto the fastpulley 2", (either by hand or by an ordinary hand-lever, not shown inthe drawings,) then builds the cop a, as shown in Figs.

1 and 2, to the full diameter desired, either in very close spiral rows,as shown at a, on the right hand of Fig. 4, or, as preferred, in widercoils, as shown to the left of Fig. 4:, which latter makes a firmer a-ndmore elastic cop, less liable to be broken in handling while beinginsorted into the shuttle.

As each cop a is so built and finished, the belt 5 is shifted onto theloose pulley 2"', and shown in this position in Figs. 1 and 2, when thetapered part of the spindle 1' is drawn back out `of the cop a by thedrawing-head 1lll against the power of the spring 13, on the smallguide-spindle 13 behind it, (to the position indicated in dotted linesin Fig. 1,) by one hand of the operator, so that the cop is then removedby the other hand, when the sp1-ing 13 presses back the spindle 1 to itsoriginal position, ready for winding another cop, a, as hereinbeforedescribed, with the point 1 in the guide-disk 10, all ready forattaching a,

new thread and winding a fresh cop, a.

This new or improved winding machine or mechanism, shown in Figs. 1 and2 of the accompanying sheet of drawings, for the making of hollow copsof thread for the shuttles of sewing-machines, is described as of thesimplest form for winding one cop at a time, and to be attached to eachsewing-machine table, or other table suitable for the users orconsumers, for winding the cops for one or more machine-s. But to renderthese machines suit-v ab'e for threadmanufactures-to wind these improvedhollow cops, and supply `them to the sewing-machine users ready forinsertion into the shuttles, they may be made with a winding-spindle, 11', fixed in the spindle 1" or 2, and steadying-center 10, andhead-stock or standard 10' at the other or left side, instead of thesliding rod and spindle 13 13', and having a thread-holder and spring,12, with another bell-crank, 9,s and layingon 1inger 9", actuated by thefirst, or direct from the heart-motion 8 S', so that two cops, a, couldthus be wound at the same time, thus doubling the production by thesealterations, while the cops may be removed automatically by the slidingout of the centers -10 or heads 10', and the lingers and the hand of theoperator after drawing back the centers. By

the following simple means four such cops may be wound atonceon thismachine, through I the use of duplex or double ended portablewinding-spindle I I' shown in Fig. 5, instead of the fixed spindle 1 l'at each side of the machine, one such, by its square end 1", beinginserted in cach-of the ends 11 11' of the spindles 1 and 2, and therebeing double bellcranks 9, and laying-on fingers 9", in this case ateach side, the end of each thread, after passing through the eyes of thelatter, would be wound round its respective spindle, and fixed on theholding-spring 1"' of the small cross-head I, of and betweeneach pair ofspindles I I', when the band 5 would be set on, and a cop, a, would bewound on each of these spindles, as indicated in dotted lines in Fig. 5,at both sides ofthe machine,the portable spindles being removed by thesimple pressing back of its steadying-center 10, in this case fittedwith a spring behind it for that purpose, when the cops would be removedand the spindles reinserted, and four new cops Wound at once,allsubstantially as stated, and particularly described in reference to,and shown in, Figs. 1 and 2.

The copsv a can be Wound to any length andj -fvl diameter to suitparticular sizes of shuttles, by making the spindles 1 l' or I l' longeror shorter, and a correspondingly longer or shorter traverse be given tothe bell-cranks and tin.; gers 9 9", by shifting the pin in the slot ofits lower arm 9', to which the connecting-rod S" is'attached, andwinding for a longer or shorter time, to give a larger or smaller sizeof cop;

and when the cops are built to their full diameter they could be made toset the catch of a spring or weighted lever free to throw the band ontothe loose pulley, and stop the winding until the cops were removedandthe spindles reset for winding fresh cops.

I claimy The combination, with a revolving spindle for winding acylindrical cop, ofa holder upon the spindle beyond the portion thatreceives the cop, substantially as speeilied, whereby the inner end ofthe thread is caused to project from the inside of the cop,substantially as set forth.
